bar raisers

I used these: https://www.demon-tweeks.co.uk/Product.do?method=view&n=699&g=379772&p=379781&d=124&c=4&l=2&utm_source=Google&utm_medium=Base&utm_campaign=Handlebars&gclid=EAIaIQobChMI97DgzOzq2wIVw7gbCh1BTA1aEAQYAyABEgKxLvD_BwE&gclsrc=aw.ds

Slotted to suit different bolt centres, but bottom component locates securely.

Result is just visible at upper left of attached pic -- not cheap, but effective for me (ironically, after fitting these I came across the one-off risers that came with the Fastback I had 40 years ago ... )

I've used some bar risers on my 99 as the original position with the flat bars was a little too low for me and the serious annoyance of the cable routes over the fork tops.

Got them off ebay https://www.ebay.co.uk/itm/Handlebar-bar-riser-kit-Multi-4-stage-Trials-Enduro-MX-Touring-22-2mm-7-8-22mm-/181561997036?hash=item2a45f036ec the fit was perfect with some SS BSF Allen capped bolts and I didn't need to do any fettling at all.

I simply fitted handlebars with a slight rise, around 1". Much simpler

Simpler, perhaps, but I want to keep the width of the bars to the absolute minimum, so "straights" are what I want â incidentally, not Norton straights, but from an MZ TS250/1.

My handlebars are Manx. No, not Manx Norton, but Manx. That's the brand name of the maker, in New Zealand. The company owner was a Norton owner, and I believe, started making bars because he needed the particular bend used on International Nortons. I have a flat and a slight rise bar. Sadly the maker's sticker has come off....

All I can say is that I didn't have any such problem with my set.

The Demon Tweek Risers are a poor fit and result in the bolts getting bent when tightening up . Would not recommend unless you have the skill to re-shape to a better fit.

Mine are fitted to a Commando, so it's clearly possible that other Norton variants would lead to a different experience. The ones I got were slotted to accommodate different bolt spacing (arguably not entirely desirable, since the upper sections of the risers depend on clamping force to keep them in position).

Do you have photos? I'm having difficulty visualising what your problem was, exactly.

Hi Julian, they went on ok and all seemed well, but taking them off to work on forks showed a problem with hole centers and profile to the top yoke. It may be that you have NORTON forks and I have " improved" AMC made norton !!. Or possibly DT's have changed the profile.

OK, I think I've got it now; put another way, the problem is excessive size of the riser element intended to fill the half-round part of the clamp formed in the yoke, thus leaving the ears of this part in mid-air rather than abutting the flat area around the bolt holes?

As you say, the only easy fix would be packing pieces.

Mine were fitted to a late Atlas and the bottom piece drops into the yoke fine except it leaves a gap to the yoke under the slotted section. If not spotted when the bolts tightened the slots(which are not wide enough) crush the bolts ,bending them. Going to make some packing pieces and refit with new bolts. Std Atlas Yokes. The cheap risers would be a better bet,may have the same problem but at a third of the price.
